Enfrentamiento del tabaquismo en el paciente hospitalizado / Smoking cessation in the hospitalized patient

Resumen La hospitalización es una oportunidad valiosa para el abandono del tabaquismo, desaprovechada en Chile. La necesidad de hospitalizarse está determinada por enfermedades muchas veces causadas por el consumo de tabaco, este escenario permite al paciente valorar no solo las consecuencias de esta adicción, si no también, la importancia de suspender el consumo. Es esperable que durante la hospitalización aparezca el síndrome de abstinencia de nicotina, cuyo reconocimiento y manejo es fundamental para evitar complicaciones habituales: ansiedad o delirium. Por todo lo anterior, resulta necesario el adecuado enfrentamiento del tabaquismo en el paciente hospitalizado, lo que es reconocido por organismos acreditadores internacionales como Joint Commission. Un metanálisis Cochrane 2012 concluyó que los dos pilares fundamentales de las intervenciones efectivas fueron el carácter multimodal (consejería y tratamiento farmacológico), y el seguimiento ambulatorio por más de un mes posterior al alta. Los elementos centrales de una consejería breve pueden resumirse en el ABC, siendo A: averiguar sobre el consumo de tabaco; B: dar un consejo breve indicando la importancia de dejar de fumar, y C: Ofrecer apoyo para la cesación a los pacientes que se muestren motivados. Si bien las intervenciones mencionadas involucran contar con recursos para apoyo farmacológico, no pareciera haber excusas para seguir sin implementar en los hospitales chilenos intervenciones sencillas como documentar el estado tabáquico de cada paciente y ofrecer consejería breve.

Hospitalization is a valuable opportunity for smoking cessation. In Chile this opportunity is wasted. The need to hospitalize is determined by diseases often caused by smoking, this scenario allows the patient to assess not only the consequences of this addiction, but also the importance of stopping tobacco consumption. During hospitalization, the nicotine withdrawal syndrome appears, whose recognition and management is essential to avoid habitual complications: anxiety or delirium. For all of the above mentioned reasons, it is necessary the adequate confrontation of smoking in the hospitalized patient, which is recognized by international accreditation bodies as Joint Commission. A Cochrane metaanalysis 2012 concluded that the two pillars of effective interventions were the multimodal character (counseling and pharmacological treatment), and ambulatory follow-up for more than one month after discharge. The central elements of a brief counseling can be summarized in ABC, where A: ask about smoking; B: give brief advice stating the importance of quitting, and C: provide support for cessation for motivated patients. Although the above-mentioned interventions involve resources for pharmacological support, there seems to be no excuse for implementing simple interventions in Chilean hospitals, such as documenting the smoking status of each patient and offering brief counseling.

Factores asociados con el éxito de la terapia antitabaco en pacientes tratados con vareniclina: 10 años de experiencia en un programa multidisciplinario / Factors associated with success of a smoking cessation program

Background: Smoking cessation therapies include counseling, psychological management and pharmacological therapy. Varenicline is the most effective and safe medication available. Aim: To study risk factors for the failure of pharmacological smoking cessation therapy with varenicline. Patients and Methods: Retrospective analysis of 281 patients aged 45 ± 11 years (65% males) with a mean consumption of 31 ± 22 packs/year. They completed a smoking cessation program comprising psychological support and use of varenicline in a private clinic. Patients were followed with telephonic interviews during one year. A complete abstinence during one year was considered as a success of the program. Results: The success rate of the program was 53.4%. The factors associated with failure were a high tobacco dependence rate determined with the Fageström test (Odds ratio (OR) 2.47, 95% confidence intervals (CI) 1.16-5.26, p = 0.02). An instruction level of more than 12 years was associated with a lower failure rate (OR 0.38 95% CI 0.18-0.82). Conclusions: A high tobacco dependence rate and a lower education were associated with a higher failure rate of this smoking cessation program.

Revisión sistemática de estudios de costo-efectividad y análisis de transferibilidad de intervenciones sanitarias para la cesación del hábito tabáquico / Systematic review of cost-effectiveness studies and transferability analysis of health interventions for cessation of smoking

Objetivo: El objetivo de este estudio fue conocer la eficiencia de las estrategias de consejería breve (CB), terapia de reemplazo de la nicotina (TRN) y el uso de medicamentos como el bupropión y la vareniclina. Para \r\nlo cual se plantearon las siguientes preguntas de investigación: Son la consejería breve, la terapia de reemplazo de nicotina en combinación con CB y/o las terapias farmacológicas con vareniclina o bupropión asociadas a CB, intervenciones costo-efectivas en la cesación del hábito tabáquico? Son transferibles los resultados de los estudios que evalúan la costo-efectividad de la consejería breve, terapia de reemplazo de nicotina y/o terapias farmacológicas con vareniclina o bupropión al contexto chileno? Metodología: Se realizó una búsqueda sistemática de la literatura en MEDLINE y CRD (Centre for Reviews and Dissemination) de estudios publicados entre los años 2004 y 2014, que evaluaran la costo-efectividad de la consejería breve, terapia de reemplazo de la nicotina y terapias farmacológicas con bupropión o vareniclina como estrategias para el cese del hábito tabáquico en población general. Conclusiones: Todas las intervenciones evaluadas fueron costo-efectivas al compararlas con CSA. Las terapias farmacológicas asociadas a CB demostraron ser más costo-efectivas que la CB por sí sola. Vareniclina +CB resultó ser una intervención dominante en relación a sus comparadores.Vareniclina domina todas las otras terapias, por lo que debiera ser considerada como la terapia de elección en fumadores en su primer intento para dejar de fumar. La inclusión de vareniclina asociada a consejería breve en el Sistema Nacional de Salud, reduciría la morbilidad y la mortalidad relacionada con el tabaquismo en Chile, resultando en importantes ahorros económicos en salud.

Análisis crítico de un artículo: terapia de reemplazo de la nicotina, efectividad en un escenario real / Critically appraised article: A prospective cohort study challenging the effectiveness of population-based medical intervention for smoking cessation

Objective: To examine the population effectiveness of nicotine replacement therapies (NRTs), either with or without professional counselling, and provide evidence needed to better inform healthcare coverage decisions. Methods: A prospective cohort study was conducted in three waves on a probability sample of 787 Massachusetts adult smokers who had recently quit smoking. The baseline response rate was 46%; follow-up was completed by 56% of the designated cohort at wave 2 and 68% at wave 3. The relationship between relapse to smoking at follow-up interviews and assistance used, including NRT with or without professional help, was examined. Results: Almost one-third of recent quitters at each wave reported to have relapsed by the subsequent interview. Odds of relapse were unaffected by use of NRT for > 6 weeks either with (p = 0.117) or without (p = 0.159) professional counseling and were highest among prior heavily dependent persons who reported NRT use for any length of time without professional counselling (OR 2.68). Conclusions: This study finds that persons who have quit smoking relapsed at equivalent rates, whether or not they used NRT to help them in their quit attempts. Cessation medication policy should be made in the larger context of public health, and increasing individual treatment coverage should not be at the expense of population evidence-based programmes and policies.

Resultados de un programa multidisciplinario para el control del hábito tabáquico / Results of a multidisciplinary program to quit smoking

Background: Therapies to quit smoking are based on counseling, psychological therapy (PT), nicotine replacement therapy, bupropion or varenidine. Aim: To report the results of a multidisciplinary program to quit smoking Material and Methods: Patients agedl8years or more, motivated to quit smoking were admitted in a program based in counseling and PT, with or without pharmacological therapy. They were assessed by telephone during one year offollow up. Patients with unstable psychiatric diseases were excluded. Results were considered as "successful" when patients maintained abstinence during the year offollow up. A logistic regression analysis was done to identify factors associated with treatment success. Results: Between 2005 and 2011, 198 patients aged 45 ± 11 years (56% males), who smoked 31.5 ± 20.6 packages/year, were treated. Ofthese, 155 (78%) were treated with varenidine, 26 (13%) with bupropion and 17 (9%>) did not receive pharmacological therapy. One hundred sixty eightpatients completed the year offollow up. In 82 (49%>), treatment was successful and was negatively associated with a history of depression (odds ratio = 4 (95% confidence intervals 1.23-38.33). The main side effeets associated to varenidine and bupropion were nausea in 37 and 23%o, sleep disorders in 20 and 19%o and headache in 12 and 0%>, respectively Conclusions: A multidisciplinary program to quit smoking achieved a 49%> of abstinence during a year offollow up.

Qué deben saber los cardiólogos del tratamiento farmacológico para dejar de fumar? / What cardiologists should be aware of pharmacotherapy for smoking cessation?

El consumo de tabaco constituye el principal factor de riesgo reversible en la enfermedad cardiovascular isquémica y dejar de fumar rápidamente disminuye el riesgo de eventos cardiovasculares y de muerte por esta causa. Las intervenciones conductuales han demostrado ser efectivas para dejar de fumar, y si a ello se suman fármacos, al menos se duplican las tasas de abstinencia medidas al año. Los fármacos con efectividad demostrada son la terapia de reemplazo nicotínico en todas sus formas farmacéuticas, el bupropión y la vareniclina. Estos fármacos han sido estudiados en pacientes con enfermedad cardiovascular estable y tienen similar efectividad que en la población general y un adecuado margen de seguridad, por lo que se recomienda su prescripción junto a la terapia conductual. No hay evidencia de mayor efectividad al asociar diferentes fármacos ni tampoco de diferentes perfiles de seguridad. La relación riesgo-beneficio de los posibles riesgos psiquiátricos y cardiovasculares reportados y los beneficios de abandonar el consumo benefician ampliamente el uso de estos fármacos en las indicaciones recomendadas.

Factores determinantes en el éxito de un tratamiento antitabaco / Factors associated with abstinence in a smoking cessation program

Smoking cessation programs have an efficacy of approximately 30 percent. Different factors related to the patients may influence this figure. Aim To identify determinant factors for smoking cessation after one year of treatment and to determine if bupropion and nicotine substitutes are effective in smoking cessation treatments. Material and methods: Follow up of 68 patients that attended a smokers clinic at a General Hospital. The patients filled up a questionnaire which included demographic, morbid and smoking habits data. They were subjected to a psychiatric interview to determine their treatment. One year later, patients were contacted by telephone and were asked if they remained without smoking. Results: After one year, 41 percent of patients responded that they were abstinent. On univariate analysis, male gender appeared as a protective factor associated to abstinence. On multivariate analysis, the use of bupropion appeared as a protective factor. A high score on the automatic item of the smoking motivation questionnaire appeared as a risk factor. The presence of respiratory diseases and the male gender were borderline significant protective factors. Nicotine substitutes were not associated with better abstinence rates. Conclusions: In this sample of smokers, the use of bupropion was associated with better abstinence rates and a high motivation to smoke appeared as a risk factor to continue smoking.

Ambulatório de apoio ao tabagista no Ceará: perfil dos pacientes e fatores associados ao sucesso terapêutico / Outpatient smoking cessation program in the state of Ceará, Brazil: patient profiles and factors associated with treatment success

OBJETIVO: Avaliar o perfil dos pacientes e fatores associados ao sucesso do tratamento do fumante. MÉTODOS: Estudo retrospectivo dos pacientes que foram atendidos no ambulatório de apoio ao tabagista do Hospital de Messejana, no Ceará, durante o período de outubro de 2002 a abril de 2005. O tratamento foi avaliado considerando-se o perfil do tabagista, tipo de medicação e período de utilização da mesma. RESULTADOS: Do total de 320 pacientes atendidos, 65,6 por cento eram mulheres. A média de idade do início do tratamento foi de 48 anos, sendo 33 anos o tempo médio de uso do tabaco. Acima de 90 por cento deles iniciaram o tabagismo antes dos vinte anos de idade. Daqueles que se encontravam no programa havia pelo menos um ano (258 pessoas), 50,8 por cento atingiram o sucesso terapêutico, 17,8 por cento recaíram e 31,4 por cento não pararam de fumar. Sucesso parcial foi atingido, em média, na quinta semana do tratamento e a recaída foi predominante no quarto mês. Cerca de 60 por cento dos pacientes utilizaram terapia medicamentosa. CONCLUSÃO: A chance de parar de fumar foi associada significativamente ao uso de medicação, independentemente do perfil tabágico avaliado. No segundo ano do programa, observou-se maior associação da bupropiona à terapia de reposição nicotínica, com conseqüente elevação da taxa de sucesso e tendência à redução da recaída.

OBJECTIVE: To evaluate patient profiles and factors associated with successful treatment. METHODS: A retrospective study of patients enrolled in the smoking cessation program at the Hospital de Messejana, located in the state of Ceará, Brazil, from October of 2002 to April of 2005. The treatment was evaluated based on patient profile, type of medication prescribed and time on that medication. RESULTS: Of the 320 patients enrolled, 65.5 percent were women. The mean age at the outset of treatment was 48 years, and the mean duration of the smoking habit was 33 years. More than 90 percent of the patients had started smoking before the age of 20. Of the 258 individuals who had enrolled in the program at least one year prior, 50.8 percent had achieved treatment success; 17.8 percent had relapsed, and 31.4 percent had not quit smoking. On average, partial success was achieved in the fifth week of the treatment, and relapse occurred predominantly in the fourth month. Approximately 60 percent of the patients were treated with medication. CONCLUSION: Quitting smoking was significantly associated with the use of medication, regardless of the profile of the smoker evaluated. In the second year of the program, quitting smoking was more strongly associated with the use of bupropion and nicotine replacement, resulting in a higher success rate and a trend toward a reduction in the relapse rate.
